On a Johns Island job, crawl Space Mold Remediation follows from the inspection rather than preceding it — there is no point specifying this work before the source of the water is known.
There is growth on the joists or subfloor, and a smell coming up into the house.
Mold remediation on lowcountry and coastal plain ground
Humidity near Johns Island stays high enough for long enough that growth here is sustained rather than seasonal. Remediation without humidity control does not hold on the coastal plain — the space simply returns to the conditions that produced it.
Coastal Charleston County humidity is the other half of it. For much of the year the outside air here is wetter than the crawl space, so any approach that relies on ventilation to finish the job works against itself.

Mold remediation in Johns Island: common questions
Do you test the mold?
Identifying the species rarely changes what has to be done, because the response follows the extent of affected material and the moisture source. Where testing is needed for a sale or a claim, an independent hygienist is the right route, not the company doing the removal.
Will it come back after remediation in my Johns Island home?
Not if the moisture is corrected, and very likely if it is not. Around Johns Island the conditions that produced it are seasonal and recurring, so the humidity control is the durable half of the job.
Do you cover all of Johns Island?
Yes — Johns Island and the surrounding part of Charleston County, including the 29455 area. We also work in nearby Ravenel, Hollywood and North Charleston.
What should I have ready when I call about my Johns Island home?
Your street in Johns Island, when you first noticed it, and what you can see or smell — standing water, a waterline on the piers, insulation hanging down, or a floor that has gone soft. Photographs help.
How quickly does water under a Johns Island house need to come out?
Quickly. Wood starts absorbing moisture immediately and mold can establish on damp material within roughly 24 to 48 hours. In Charleston County that window is shorter in summer than in winter, because the space stays warm and humid.
Do you test the mold?
Identifying the species rarely changes what has to be done, because the response is driven by the extent of affected material and the moisture source. Where testing is needed for a property transaction, an insurance claim or a health question, that is best done by an independent hygienist rather than by whoever is doing the removal.
